Mom won't be there for grandchildren anymore

Jazminn
This is completely different than what I've done before but I had to vent. My mom who I had to fight with to help more with her granddaughter (my oldest) when I go into labor will no longer be around when the new baby is here. She has no issue picking her up to have fun but when I ask if she could help her get to school (she's in kindergarten) while me and hubby are at the hospital, she flat out refuses. There was a time where it'd be hard because of his job schedule but we're gonna be okay with that, but just the fact that she refused to help and only wanted to see my oldest to have fun is wrong to me (it takes a village). After a while, I let it go and tried to just let her have her fun time with her but then she started acting childish by not responding to my messages when I txt her, when I would ask her if she wants my daughter or wants to drop off my mail (she lives down the street from me) and ppl could be sending her pkgs for the baby (I don't trust pkgs coming to my apt because they could get stolen). I told her I'm tired of the childish acts and told her until she grows up, she can't be around. She decides to get my brother involved and they're both tag teaming me saying they demand to see my daughter and I need to act like an adult and realize they don't need to help because they didn't tell me to spread my legs and get pregnant a second time (I had a miscarriage last September). My hubby tried to work things out and he said it seems like she was beginning to understand but when I let her know about my induction date this coming Thursday, she just wanted to argue and tell me I'm wrong, she's right and she deserves an apology regardless because she's the parent, despite the ignorant crap she's said. Plus she tried to belittle my parenting by saying I'm spoiling my daughter too much and tell me what I should do but still refuses to help. I'm sick of her being ignorant and rude and not seeing her faults, I'm just ready to let it all go. At this point, if she's not around to help and to constantly belittle me with her words, yet still expect to see her grandkids, she got it backwards. I'm a little sad but I refuse to take disrespect. Sorry, rant over.
